PowerWalker VFI 15K CPG PF1 3/3 BE - 15kVA Online Double-Conversion UPS, Tower, 3-Phase, Pure Sine Wave, LCD, USB/RS-232, SNMP Slot

Delivering a full 15kW of active power with unity output power factor, the PowerWalker VFI 15K CPG PF1 3/3 BE ensures your critical 3-phase loads never miss a beat. This online double-conversion UPS provides continuous, pure sine wave output with zero transfer time, making it the ultimate safeguard for data centres, industrial systems, and enterprise infrastructure.

Overview

Engineered for demanding environments, the VFI 15K CPG PF1 3/3 BE operates in tower form factor and accepts 3-phase input (400V AC nominal) with a wide voltage range of 304–478V AC. It delivers regulated 3-phase output at 400V AC ±1% in battery mode, with auto-sensing 50/60 Hz frequency. The internal sealed lead-acid battery bank (20x 12V/9Ah) provides reliable runtime during outages, while the high-efficiency online mode (up to 95%) reduces energy costs.
